a key player in this drama, sean penn, who directly appealed to the country's president on jacob's behalf. >> jacob and his family are living a nightmare of human abuse. >> but jacob is not free to go home yet. >> i feel like i'm in the twilight zone. >> under house arrest in bolivia, suffering from parkinson's disease that came on while he was in prison, jacob told us today his life may be in danger. >> there are 13 people in prison, and those are very high government officials. things don't look good right now. there's a lot of death threats against me. >> it is the latest twist in a tale. he invested $200,000, his life savings, as a very junior partner in a rice growing venture in bolivia. it was a good business. 40 million pounds of rice the first year, 200 bolivian employees, and that, he and his defense team told us, was the reason he was targeted. he's got to start paying them money. steve moore is a retired fbi agent, he advocated for the release of amanda knox, and he's investigated jacob's case for free. here we are in front of the palace of justice. is this a place of hope for
